Jesus was feeling the squeeze from dangerous groups during the last year of his ministry. First century Tea Party Jews wanted him for a Revolution. Intensely traditional Pharisees wanted his followers. Herod just wanted an audience. All were happy to use him to their advantage, or kill him out of convenience.
The vise was closing as he heads to Jerusalem in the back half of the Gospel of Mark. Weak hands were dropping off in droves. Political revolutionaries were turning up the rhetoric and demands that Jesus assume the political role they had carved out for him. Religious leaders were ready to accept him if he was willing to vote the party line on legalism and maintain his place alongside the partisan rank and file. Even Herod would have likely allowed him to carry on as long as he didn’t disrupt the political process.
I love how Jesus refused all endorsements. He is the ultimate independent.
